The Sepia color adjustment layer simulates a photo printed with sepia colored toning. Before the complex printing process of the modern multi-tone color printer, photographs were printed in mono-tone. A common favorite color used in mono-tone photographic prints was taken from the Sepia Officinalis cuttlefish to give a warmer color to the black and white alternative. Use PhotoPad's sepia tone layer effect to simulate what your photograph may look like with different ratios of the sepia color mixed into your printer. Add a sepia tone layer by clicking the Sepia icon on the Filters tab of the toolbar, then adjust the selected sepia tone layer in the Sepia Tone Properties panel.
Use the Strength: slider to adjust the strength of the filter.
